MITERiNG- MACHINE.

SPECIFICATION forming part of Letters Patent No. 360,630I dated April 5, 1887.

Application filed August 5, 1886.

To all whom, it may concern:

Be it known that I, SAMUEL WALLER, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Mitering-Machines, of which the following is a specification.

This invention relates to machines for sawing miters either on straight or curved lines, or miters and bevels; and it consistsin the novel construction and arrangement of the saw-guides and mechanism for adjusting said guides at various curves and angles suitable for the work to be performed.

To enable others to fully understand my invention, I proceed to describe the same in detail with the aid of the accompanying drawings, in which- Figure l is atop or plan view of my machine. Fig. 2is a front elevation of the same. Fig. 3 is a crosssection on line y o of Fig. 2. Fig. 4 is a perspective View of the machine, showing one of the saw-guides removed to eX- hibit the bridge and to show the split posts.

A represents the bed of the machine supporting all the working parts. It is preferably made of iron for solidity and freedom from liability to warping or splitting, and is triangular in form.

B B are adjustable and removable guides, against which the moldings or strips to be sawed are placed and held.

Across the central part of the bed is iixed a ilatironshaped bridge, C, its center line4 being at an angle of iortyilve degrees to the aforesaid guides B B. rlhe sides of said bridge are curved, as shown in Fig. 1, the object for which is to permit the saw-guides to be bent or curved, by drawing and iixing their front ends toward each other in adjusting said guides to any required curved lin'c without the bridge interfering therewith.

Near the rear side ofthe bed, and at the heel of the bridge, are made two slots, D D, in which are adjustably fixed posts E E, their bases being secured by means of set-screws c e. At the front side of the bed and at the toe of the bridge are made two curved slots, F F, in which are adjnstably iixed posts G G. The posts are split from their tops down to the bases to provide a space for the saw to play in. The posts G G are adjustably secured in the slots, by means of setescrews g g, in like manner to the posts E E. To the top part of the posts are attached thin sheet-metal ilexible sawguides H H, consisting of two strips Serial No. 210,038. (No model.)

Xed in the split and held in position by means of loops It h, attached to said strips and embracing the top parts of theposts, resting on shoulders 7i' thereon. Across the top of the bridge is made a slot, J, in which two slotted brace-pieces, K K, are adj ustably secured by means cf set-screws la lo, the upright arm Z of said brace-pieces bearing against the inside surfaces of the said flexible strips H H. By this means the saw-guides may be bent or curved to conform to any degree of curvature required to saw a given curved joint. Thesaw playing in between the said strips enables the workman to readily adjust the guides to make a perfect out.

The molding or piece to be sawed is placed against one of the guides B B for sawing a common miter. In the heel of the bridge piece are placed two screws, S S, the purpose of which is to provide adjustable bearing, against which a short piece of molding rests, for the purpose of sawing an Octagon miter, the guides B being removed to make room, and in the top of the bridge is placed a vertical screw, S', designed to provide a stop or pressure-bearing to hold the piece iirmly in place while being sawed.

From the foregoing it will be seen that the saw-guides may be set to any required degree of curvature by setting the forward posts at the given point in the curved slots, a scale in connection with said slots readily enabling the proper degree to be found, and the bracepieces K K adjusted to spring the iiexible strips II II outward to suit the curve, whereby a curved cut may be made with the saw, or the said saw-guide pieces may be set in a straight line for sawing a straight niiter, at the pleasure of the operator.

Having described my invention, I claim- The combination, with the bed-plate A,provided with the adjustable guides B B, and having the slots D D and F F, of the split posts E E and G G, adjustably iixed in said slots and carrying the flexible saw-guides H H, and the bridge C, provided with the crossslot J, having the adjustable brace-pieces K K, all constructed and arranged substantially as described, whereby the said guides may be adj usted to straight and curved lines, as and for the purpose specified.

SAMUEL VALLER.
